X-Git-Tag: rev_ivi_2015_02_04~10849
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3725df41dcebdecb0eb4faba307ed31d41ed2394;p=scm%2Fbb%2Ftizen-distro.git

makedevs: rectify the exit codes and handle the invalid parameter

It is correct behaviours to output help and version information,
and should return 0;
When input parameter is invalid, print help information and exit.
